Variance components for greasy fleece weight in Rambouillet sheep were estimated. Greasy fleece weight was modeled either as repeated measurements on the same trait or as different traits at different ages. The original data were separated according to the age of the ewe at shearing into three classes; 1 yr, 2 and 3 yr, and older than 3 yr. An animal model was used to obtain estimates of geneti...

BACKGROUND It is not clear whether in old people with end-stage renal disease kidney transplantation is superior to dialysis therapy. METHODS We compared mortality rates between kidney transplant recipients (KTRs) and the general population across different age categories. We also examined patient and allograft survival in 15 667 elderly KTRs (65-<90 yr old, 36% female) within three age subgr...

This study aimed to assess the immune status of the Korean population against hepatitis A virus (HAV). Residual serum samples from 2008 to 2010 were collected from diagnostic laboratories and a total of 1,872 samples were analyzed. Anti-HAV seroprevalence was 57.3% in subjects aged 1-4 yr, 69.8% at 5-9 yr and decreased to 38.8% at 10-14 yr, 13.0% at 15-19 yr, and 11.7% at 20-29 yr. Seroprevalen...

hemorheology specialists believe that athletes of different sport fields have different hemorheological patterns. the aim of this study was to investigate the effect of sport field on hemorheological variables following acute aerobic exercise. athletes were divided into three groups of 15 subjects (endurance runners: mean±sd: age 24.6±5.2 yr, bf% 6.8±1.6, bmi 21±1; football players: age 22.5±1....

BACKGROUND Evidence from randomized trials on the effects of screening for prostate cancer (PCa) on disease-specific mortality accumulates slowly with increasing follow-up. OBJECTIVE To assess data on PCa-specific mortality in the Rotterdam section of the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial. DESIGN, SETTING, AND PARTICIPANTS A randomized controlled trial...

BACKGROUND An increasing number of elderly patients are treated for aneurysmal subarachnoid hemorrhage. Given that elderly age is associated with both poor outcome and an increased risk of hydrocephalus, we sought to investigate the interaction between age and hydrocephalus in outcome prediction. METHODS We enrolled 933 consecutive patients treated for subarachnoid hemorrhage between 2002 and...

OBJECTIVE The age at which a child receives a cochlear implant seems to be one of the more important predictors of his or her speech and language outcomes. However, understanding the association between age at implantation and child outcomes is complex because a child's age, length of device use, and age at implantation are highly related. In this study, we investigate whether there is an added...
